Root Canal Treatment Process
Hello Dr.
Lin, I recently started root canal treatment and noticed that this dentist's approach is quite different from my previous one.
Below is a comparison based on the symmetrical positions of the teeth (high likelihood of double roots).
I understand that cleaning the molars is more challenging.
My previous dentist (who is nearing retirement and no longer accepts patients needing root canal treatment) seemed to start cleaning the pulp directly after administering anesthesia.
The endodontic files would enter the canal multiple times and rub against the walls repeatedly.
After filling with temporary material, the second session would occur in about 3 to 4 days, and this method resulted in no sensitivity in the treated tooth post-operatively.
The current dentist: After administering anesthesia, the endodontic files only entered the canal about six times, each time for just a second or two before being removed.
Then, medication was placed for about two weeks before the follow-up appointment, stating that a neurotoxic agent was used.
After the post-operative swelling and pain subsided, the tooth still experiences spontaneous pain and sensitivity.
I found some information online indicating that placing medication to kill the nerve is intended to avoid anesthesia, but in this case, the dentist did administer anesthesia and still did not directly remove the pulp, leading to ongoing sensitivity and discomfort.
I would like to know if using medication to kill the nerve is better in the long run? I am considering asking the dentist to directly remove the pulp after anesthesia during the next root canal treatment, but I am concerned about offending the dentist.
Thank you for your clarification, and I wish you good health, peace, and happiness!

Hello: Each physician's treatment methods or guidelines can indeed vary, making it difficult to comment on their effectiveness or correctness.
However, since you have chosen a new physician, it is advisable to follow their approach to complete the treatment, as ultimately, the new physician will be responsible for the success or failure of your root canal therapy.
You may gently inform them that you are still experiencing pain despite the medication, and ask if additional mechanical or manual debridement is necessary.
Alternatively, if you no longer trust the new physician and do not wish to continue treatment with them, requesting a referral to a dental pulp specialist at a medical center to complete the treatment is also a viable option.

Understanding root canal treatment (RCT) is crucial for patients experiencing dental issues, especially when comparing different approaches taken by various dentists. The essence of RCT is to remove infected or damaged pulp from the tooth, clean the root canals, and seal them to prevent future infections. However, the techniques and philosophies behind RCT can vary significantly among practitioners, leading to different patient experiences and outcomes.
In your case, it seems you are observing two distinct methodologies in the RCT process. The first dentist, who is now retired, employed a more aggressive approach, immediately cleaning the pulp after administering anesthesia and using the files multiple times to ensure thorough cleaning. This method, while effective for some, may not always allow for adequate healing time between visits, especially if the infection is severe. The quick turnaround between appointments (3-4 days) might have contributed to the lack of sensitivity post-treatment, as the tooth was likely cleaned and sealed promptly.
On the other hand, your current dentist is taking a more conservative approach. By allowing a period for the medication to work (often referred to as "medicament" or "interim medication"), the dentist aims to reduce inflammation and infection before proceeding with further cleaning and sealing. This method can be beneficial in cases where the infection is extensive, as it allows the body to respond to the treatment before further invasive procedures are performed. However, it can also lead to prolonged sensitivity and discomfort, as you've experienced.
The use of medicated materials in root canals is a common practice. These medications, often containing calcium hydroxide or other antimicrobial agents, are designed to disinfect the canals and promote healing. While this approach may lead to a longer overall treatment time, it can be advantageous in reducing the risk of complications associated with immediate sealing of the canals, especially in cases of severe infection.
Regarding your concerns about the sensitivity and discomfort following the current treatment, it is not uncommon for patients to experience some level of pain or sensitivity after RCT, particularly if the procedure was not completed in one visit. The presence of lingering pain can indicate that the infection has not been fully resolved or that there is still inflammation in the surrounding tissues. It is essential to communicate these symptoms to your dentist, as they may need to adjust the treatment plan or consider additional interventions.
When considering whether to request a more aggressive approach in your next RCT, it is vital to have an open dialogue with your dentist. Express your concerns about the sensitivity and discomfort you are experiencing and discuss the potential benefits and risks of both approaches. A good dentist will appreciate your input and work with you to find a treatment plan that aligns with your comfort level and medical needs.
In conclusion, both approaches to root canal treatment have their merits, and the best choice often depends on the specific circumstances of the tooth being treated, the extent of the infection, and the individual patient's response to treatment. It is crucial to maintain clear communication with your dental provider, ensuring that you feel comfortable and informed throughout the process. Ultimately, the goal is to preserve the tooth and restore its function while minimizing discomfort and the risk of future complications.
